Popis:	An asymmetric bidentate Schiff-base ligand (2-hydroxybenzyl-2-furylmethyl)imine (L–OH) was prepared. Three complexes derived from L–OH were synthesized by treating an ethanolic solution of the appropriate ligand with an equimolar amount of metallic salt. Three complexes, Cu2(L–O−)2Cl2 (1), Ni(L–O−)2 (2) and Co(L–O−)3 (3), have been structurally characterized through elemental analysis, IR, UV spectra and thermogravimetric analysis. Single crystal X-ray diffraction shows metal ions and ligands reacted with different proportions 1 : 1, 1 : 2 and 1 : 3, respectively, so copper(II), nickel(II), and cobalt(III) have different geometries.
